Hey guys,
I recently added a Fosgate 12 inch in a sealed box to my system in place of the crappy stock 8 ohm 8 inch.
I am using the stock Kenwood 529 S amp to power it.
A lot more bass, but i find now when i crank the volume, the sub overpowers the rest of the system quite badly.
I have turned the bass down on the head unit, but have come to the realization that i need MORE POWER!
Now, Option #1: I can pick up another 529 S to run either the 2 front doors, or all 4 doors. Running all 4 doors would have the amp running at 2 ohm stereo which it is capable of doing.
Option #2: I am picking up an MTX Thunder 302 amp., which i want to use to run just the 12 inch sub. I would then move the 529 S to the front doors or all 4 doors.
I would prefer option #2, but am worried again that the sub might drown out the fronts.
Opinions are welcomed on setup and whether to run all 4 doors off the 529 S or just the fronts, with the head unit powering the rears.

P.S. The reason those are my amp options is that i am buying them used and have deals in the works for both.
Here are the specs on the amps:
Kenwood 529 S: KAC529S
A medium power amp such as the 40 watt x 2 channel KAC-529S 2-Channel Power Amplifier is great for running sub-woofers or mid to high frequency drivers. The bridged power output is 120 watts x 1 channel and the maximum power output is specified at 250 watts. The supply is based on MOSFETs and uses two secondary capacitors and a toroidial noise filter. Features include 2-ohm stability, speaker level inputs, speaker relay protection circuitry, and a Quiet Turn-On circuit.
Product Features :
* Ground Isolation Circuit
* Power MOSFET Switching Power Supply
* Stereo, Mono, or Tri-Mode Operation
* Bridged Power Output at 14.4V (1kHz, 0.8% THD): 120 Watts x 1
* Maximum Output Power: 250 Watts
* Power Output at 2 Ohms, at 14.4V (1kHz, 0.8% THD): 60 Watts x 2
* Power Output at 4 Ohms, at 14.4V (20Hz-20kHz, 0.08% THD): 40 Watts x 2
* 2-Ohm Stable
* 2 or 1 Channels of Amplification
MTX Thunder 302:
RMS Power measured at 12.5 Volts DC:
75 Watts x 2 into a 4 Ohm load with less than 0.05% Thd+N
150 Watts x 2 into a 2 Ohm load with less than 0.1% Thd+N
300 Watts bridged into a 4 Ohm load with less than 0.1% Thd+N
Dynamic Power (IHF-202 Standard) measured at 14.4 Volts DC
120 Watts x 2 into a 4 Ohm load
212 Watts x 2 into a 2 Ohm load
425 Watts bridged into a 4 Ohm load
Signal to Noise Ratio: 110dB A-Weighted
Damping Factor: >200
Frequency Response: 20Hz-20kHz 0.25dB
Maximum Input: 8Vrms
Thunder EQ: Variable Bass Boost (0-18dB) centered at 40Hz
Crossover: Variable 40Hz to 200Hz, 12dB/octave high pass,
24dB/octave low pass with mono output
Thanks!
